Ports over majority of functionality from D7 module. Hooks work so you can add your own custom validators. Included filters and validators (formerly: rules). Some of these rely on deprecated functionality and will need to be fixed. These will all be updated in future alpha versions.
Dev branch of this module. Currently being built as a direct port over, with changes mostly relating to change in D8 syntax and new usage of objects.
Full conversion to object oriented approach may and would occur in 8.x-2.x dev branch, although viability is to be determined. What is nice is that custom filters and validators can be added via the hooks system in Drupal, which is very useful.
